The preparation of PAn/CA composite conductive membrane by in-situ permeating chemical polymerization was introduced in this paper. By this method, polyaniline was synthesized onto the pore wall of the CA microporous membrane. The influence of preparing conditions on the conductivity and apparent selectivity of CO 2/O 2 was investigated. The pore size and distribution of the resulting membrane were evaluated by the method based on bubble pressure and liquid permeation. SEM, FTIR were employed to character...
